Drought Vulnerability Classification

Adequate System – There is greater than a 90% probability that the community will not experience any water shortages or threat thereof during a severe drought similar to the drought of record.

Drought Adequacy Description

If a drought similar to the 1953 drought of record were to recur today, it is estimated with 50% confidence that the current system would be able to support a demand of 0.34 mgd (the mid- or best yield estimate).
It is estimated with 90% confidence that the current system would be able to support a demand of 0.23 mgd.
Because the system would be able to fulfill the community’s current demand of 0.08 mgd with 90% confidence, the drought vulnerability of the system is classified as ADEQUATE.
